Reverse Pendulum Serve faults

I noticed, most players, when they throw the ball for the RPS, the ball does have quite an arc, which should be judged incorrect by the umpire. The only person who does this serve ok is to me Timo Boll. His way to do it is absolutely not mainstream but seems to me the correct one. Zhang Jike, Fan Zhendong, Marcos Freitas and many others make in my opinion a Fault.

Hi Marcin,

I agree with you on this one.  Most players throw the ball into themselves quite a lot.  They start on the middle line and hit the ball near the side line so it must be a foul throw.  Perhaps a change of rule or better policing of it is the answer.
